Step 340: 33222 + 98 = 33320
Step 341: 33320 + 98 = 33418
Step 342: 33418 + 98 = 33516
Step 343: 33516 + 98 = 33614
Step 344: 33614 + 98 = 33712
Step 345: 33712 + 98 = 33810
Step 346: 33810 + 98 = 33908
Step 347: 33908 + 98 = 34006
Step 348: 34006 + 98 = 34104
Step 349: 34104 + 98 = 34202
Step 350: 34202 + 98 = 34300
Step 351: 34300 + 98 = 34398
Step 352: 34398 + 98 = 34496

So, 98*352 = 34496
